Application March 14, 1933, Serial No. 660,736

1 Claim.

The invention relates to a nozzle construction and more especially to scalp cooling and drying apparatus nozzles.

The primary object of the invention is the provision of a nozzle of this character, wherein the construction thereof is such as to permit the application to a hair cooling and drying apparatus at the air outlet nipple of the same and said nozzle has a mouth formation which permits the convenient entrance thereof between the head of a person and the pad constituting a part of the equipment for hair waving or the permanent wave method, whereby the air, either cold or hot, can be directed so that the steam will be driven out from between the head of the person and such pad during the hair curling operation.

Another object of the invention is the provision of a nozzle of this character, wherein the construction thereof is novel, particularly with respect to the outlet tip or mouth thereof for enabling the quick drying of the hair of a person during the hair curling process or method, for example, when permanent waving the hair.

A further object of the invention is the provision of a nozzle of this character, which is simple in construction, thoroughly reliable and eflicient in its purposes, readily and easily applied and removed from a hair cooling and drying apparatus, strong, durable, and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention, and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure 1 is a side elevation of a hair cooling and drying apparatus of the hand type showing the nozzle constructed in accordance with the invention and in section applied thereto.

Figure 2 is a side elevation of the nozzle.

Figure 3 is a plan view of the same.

Figure 4 is a sectional view on the line 4-4 of Figure 1 looking in the direction of the arrows.

Figure 5 is a sectional view on the line 5-5 of Figure 3 looking in the direction oi the arrows.

Figure 6 is a View similar to Figure 2 showing a slight modification of the nozzle.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

' Referring to the drawing in detail, A designates generally a standard type of hair cooling and drying apparatus and includes the housing or casing 16 for the blower fan which is motor driven, the motor being indicated at 11. The housing 10 as usual has formed peripherally thereof a tangentially disposed air outlet nipple 12, while the motor casing is unitary with a handle 13, the electric current conductor lead 14 being extended through said handle and the said motor 11 is controlled by a switch operated from a key 15 so that the motor can be turned off or on and also the air current be rendered cold or hot under the setting of the switch 15 as is common.

The nozzle constituting the present invention comprises an outwardly tapered or conical-shaped tubiform body 16. This body 16 has a straight nipple coupling end 1'? which is split 1ongitudinally for the expansion and contraction of such end. At the split are formed ear extensions 18 having fitted therein a nut carrying bolt 19. When the end 17 is telescoped over the nipple and abuts the stop rib 20 formed thereon, such end 17 can be securely fastened in embracing this nipple end 12 for the mounting of the nozzle body 16 thereon.

The smaller end of the nozzle body 16 has integrally formed therewith the throat 21 of a mouth 22, the throat 21 being gradually flattened at opposite sides and reversely tapers with relation to the nozzle body 16, while the mouth 22 has a flat top 23 and a concaved bottom 24, the mouth 22 being correspondingly flattened relative to the throat 21. The concaved bottom 24 in its conformation fits the head of a person in the use of the nozzle for the cooling and drying step in the method of curling or permanent waving the hair during the use of the apparatus A.

The flat top 23 of the mouth 22 at the discharge end 25 of the latter has a lip or tongue 26 which functions to lift the pad or pads employed during the steaming of the hair in the permanent waving or curling process so that the mouth 22 can be presented beneath such pad or pads and the head of a person being treated to enable the blowing off of the steam from beneath the pad and in this manner eliminating the hand lifting of such pad or pads or inconvenience when using the apparatus A for the cooling and drying of the treated hair. The lip or tongue 26 has the outer rounded corners 2'? to avoid any possibility of injury when introducing the mouth 22 between the head of a person and the pad or pads during the hair curling or permanent waving process.

In Figure 6 of the drawing there is shown a slight modification of nozzle wherein the coupling means at the coupling end for frictionally binding the same upon the nipple, a flattened tip at the smaller end of said body, one side of the tip being curved, and a lip at the other side of said tip and outwardly extended for a distance therefrom, the lip having a rounded outer edge and opposite outer corners.
